摘　　要：采用高温熔融法制备了Dy3+掺杂硼硅酸盐玻璃,通过测试激发光谱和发射光谱,研究了其光谱性质.研究了玻璃组分及Dy3+掺杂浓度对发射光谱及发光强度的影响,并计算了色坐标,均位于白光区域.通过改变玻璃组分及掺杂浓度,调节黄、蓝发射峰的强度比,在387nm长紫外光激发下实现了单一基质上有效的白光发射.In this paper, the Dy^3＋-doped borosilicate glasses are fabricated by high-temperature melting method. The excitation and emission spectra of the glasses are measured to discuss their spectroscopic properties. The effects of the glass composition and the Dy^3＋ doping concentration on the emission spectrum and the luminescence intensity of the sample are investigated. We also calculate their color coordinates, which are all in the white region. By adjusting the intensity ratio of the yellow band to the blue band, which varies with the composition of the glass host and the doped concentration of Dy^3＋ ions, we implemente the effective white light on a single host under the excitation of 387 nm long-wavelength UV.
